    I have built an app with RocksDB and QtWidgets on Linux. Everything builds fine, but I get a SIGABRT when running. It happens before main() is called. This happens without actually calling any of the RocksDB functions. Just adding a single RocksDB include file will cause it. I am assuming that it is a static initialization issue as main has not started running yet. All of the example command shell programs work fine so I know the library has compiled successfully, but they do not use QtWidgets. I have listed all libraries. The RocksDB library is properly registered and the app is associated with it.

    I am using QT Creator 4.7.1 with gcc 5.3.1 on Linux Mint 18.1 64 bit.

      @BillCollins Try to start your app with strace:

      $ strace ./my_app

      Maybe you will see what happens, you can post the output here.
      Could be that the libs you're using cannot be found by the linker.

        Hi,

        To add to @jsulm, you can also call ldd your_app_name to check whether a library can't be found by the loader.

          @jsulm Thanks for your help. I ran strace. The results were larger than what fits here. The top half was loading libraries. All accesses to libraries were ultimately successful. Here is the output after the loads:

            Hi,

            To add to @jsulm, you can also call ldd your_app_name to check whether a library can't be found by the loader.

            @SGaist Thanks for the response. I ran ldd and all libraries were found.

              tcmalloc ?

              This reminds something, but I'm not sure... Try to pre-load it before starting your application using LD_PRELOAD.

                @SGaist I rebuilt the RocksDB library and added a flag to not use tcmalloc. It no longer shows up when I run ldd. But when I run ldd on my basic app, it is loaded there. Not sure why or how. But still get the same crash.

                I have tried to use LD_PRELOAD to load tcmalloc and jemalloc separately. Neither had any effect. I am now trying to learn how to use GDB to debug the static init code that runs before main to see if I can follow what is happening.

                I know it is a lot to ask, but if anyone can try to build a RocksDB app with Qt on Linux I would really appreciate it. And as I have done, no code calling RocksDB is necessary. Just include a RocksDB .h file.
